Subject[PATCH 3/3] dt-bindings: Convert Arm Mali Utgard GPU to DT schema
Date
Convert the Arm Utgard GPU binding to DT schema format.

'allwinner,sun8i-a23-mali' compatible was not documented, so add it.

-ARM Mali Utgard GPU
-===================
-
-Required properties:
- - compatible
- * Must be one of the following:
- + "arm,mali-300"
- + "arm,mali-400"
- + "arm,mali-450"
- * And, optionally, one of the vendor specific compatible:
- + allwinner,sun4i-a10-mali
- + allwinner,sun7i-a20-mali
- + allwinner,sun8i-h3-mali
- + allwinner,sun50i-a64-mali
- + allwinner,sun50i-h5-mali
- + amlogic,meson8-mali
- + amlogic,meson8b-mali

- + rockchip,rk3228-mali
- + rockchip,rk3328-mali
- + stericsson,db8500-mali
- + hisilicon,hi6220-mali
-
- - reg: Physical base address and length of the GPU registers
-
- - interrupts: an entry for each entry in interrupt-names.
- See ../interrupt-controller/interrupts.txt for details.
-
- - interrupt-names:
- * ppX: Pixel Processor X interrupt (X from 0 to 7)
- * ppmmuX: Pixel Processor X MMU interrupt (X from 0 to 7)
- * pp: Pixel Processor broadcast interrupt (mali-450 only)
- * gp: Geometry Processor interrupt
- * gpmmu: Geometry Processor MMU interrupt
-
- - clocks: an entry for each entry in clock-names
- - clock-names:
- * bus: bus clock for the GPU
- * core: clock driving the GPU itself
-
-Optional properties:
- - interrupt-names and interrupts:
- * pmu: Power Management Unit interrupt, if implemented in hardware
-
- - memory-region:
- Memory region to allocate from, as defined in
- Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt
-
- - mali-supply:
- Phandle to regulator for the Mali device, as defined in
- Documentation/devicetree/bindings/regulator/regulator.txt for details.
-
- - operating-points-v2:
- Operating Points for the GPU, as defined in
- Documentation/devicetree/bindings/opp/opp.txt
-
- - power-domains:
- A power domain consumer specifier as defined in
- Documentation/devicetree/bindings/power/power_domain.txt
-
-Vendor-specific bindings
-------------------------
-
-The Mali GPU is integrated very differently from one SoC to
-another. In order to accomodate those differences, you have the option
-to specify one more vendor-specific compatible, among:
-
- - allwinner,sun4i-a10-mali
- Required properties:
- * resets: phandle to the reset line for the GPU
-
- - allwinner,sun7i-a20-mali
- Required properties:
- * resets: phandle to the reset line for the GPU
-
- - allwinner,sun50i-a64-mali
- Required properties:
- * resets: phandle to the reset line for the GPU
-
- - allwinner,sun50i-h5-mali
- Required properties:
- * resets: phandle to the reset line for the GPU
-
- - amlogic,meson8-mali and amlogic,meson8b-mali
- Required properties:
- * resets: phandle to the reset line for the GPU
-
- - Rockchip variants:
- Required properties:
- * resets: phandle to the reset line for the GPU
-
- - stericsson,db8500-mali
- Required properties:
- * interrupt-names and interrupts:
- + combined: combined interrupt of all of the above lines
-
- - hisilicon,hi6220-mali
- Required properties:
- * resets: phandles to the reset lines for the GPU
-
-Example:
-
-mali: gpu@1c40000 {
- compatible = "allwinner,sun7i-a20-mali", "arm,mali-400";
- reg = <0x01c40000 0x10000>;

- interrupt-names = "gp",
